Map Hacks

From TibiaAuto

Reveal water with no fish

Will change the ID of non-fishy tiles to lava so you know not to fish there.
This may cause the minimap to be draw orange instead of blue tiles for water in some rare instances.

Always show creature name/hp bar

Will allow Tibia to show the name and hp bar of creatures on floors below you.
This ranges only as far as the X-Ray goes since some tile information is not available(ie underground tiles when above ground)

Multi-level Minimap Research

This fills in Tibia's minimap just as accurately as Tibia itself.
It will fill in all available floors (all 8 if above ground and all 5 if underground)
So it will automatically explore roofs and perhaps some hidden or unreachable caves.

It doesn't make any mistakes or accidentally 'shift' the map if you're walking fast. It also doesn't leave gaps and only fills in map when you move. There is a shortcomming however, if Tibia changes the map, then it will not revert researched colour points to black points. It simply takes too long to check what's not there rather than what is there.
